Hmm. The use case of linking to a specific location in a document, really appears to be more of an issue with websites not actually using ids that could be anchored to. If every paragraph had an id, you could get 95% of the way to the desired functionality by just making it easy to copy a link to e.g. www.example.com/foo#paragraph4.

At this point, Wikipedia is one of the few websites I use regularly that actually works in this way.

What? A DNS lookup doesn't include anything but the hostname and anything following a hash is never sent with a request from the browser.

It seems that “privacy researcher at brave” is a job requiring no domain knowledge, only plentiful contact with credulous journalists.

I don't want to derail this thread, but that's kind of Brave's whole MO. They pretty much constantly put out or source anti-Google content; there's often a grain of truth somewhere in many of them, but not always and rarely reported honestly.

Earlier quoted context omitted.

I think the idea there is that there would be lazy-loaded content from another site that would only load when someone scrolled far enough to see the highlighted word, which will automatically happen with this feature. The title of the Forbes article is too hyperbolic for my tastes and while this could be a security concern in very specific situations it's being overblown.

I think that would need to be a designed attack, not something that would apply to 99% of websites. The only legitimate resource (that could be used as a canary) being loaded far down a page would be an image (and that kind of requires it to be lazy loading as well).

Latest Chrome defers out-of-viewport images on its own, or at least tries to.

Confused. As I understand it, anything after the # in a uri isn't sent over the wire. So the only way someone could see that you're navigating to a specific fragment is some sort of deep chrome logging, or chrome plugin, etc. And if that's the case, cat's already out of the bag for everything you do already.

I was confused as well. I think (from some other comments) that the issue is that you can scroll to text that is specific to you and others might not have on their page (e.g. 'cancer' on some medical page) and then somehow gather from the requests that you scrolled there. It seems pretty hypothetical, but I can see the issue with forcing a scroll depending on what text is on the page, I guess.

Could someone explain this a bit better? I've read two articles on this this morning and I still don't understand what the privacy concerns are with this feature. Thanks!

The feature in question is the ability to use fragment (# in a URL) to link to matching text rather than just an ID. Here is the key line with the so-called privacy concern.

"Consider a situation where I can view DNS traffic (e.g. company network), and I send a link to the company health portal, with [the anchor] #:~:text=cancer. On certain page layouts, I might be able [to] tell if the employee has cancer by looking for lower-on-the-page resources being requested.”

So they could send someone a link to a page with a fragment, trick them into clicking it, and matching text and watch for DNS requests being lazy-loaded to learn the fact that they clicked it.

It's convoluted nonsense.

EDITED and hour later: A couple of people have pointed out it's back, they've made some changes and marked it as public now. There was another article on this same topic this morning with this: "Google's engineers have not ignored worries about the security and privacy risks. To their credit, they've gathered them together into a single document and they've clearly been engaged in understanding what people are worrie…

It's available and listed as (PUBLIC) in the title now.

As you broaden your domains of expertise, it becomes increasingly clear that most news media is astroturf.

The quote about DNS seems wrong to me ""Consider a situation where I can view DNS traffic (e.g. company network), and I send a link to the company health portal, with #:~:text=cancer," he wrote. "On certain page layouts, I might be able [to] tell if the employee has cancer by looking for lower-on-the-page resources being requested."" I thought DNS requests just get the domain, not the hash and not even the page reque…

It just seems to me like not that big a concern.

eg on a company network, it would be common to install an SSL cert on all devices on the private network for things like web proxies, CASBs, or other security policy enforcement measures.
